Abstract
Coronary artery vasospasms have been known to cause episodic angina pectoris, along with ST-T wave changes. In addition, vasospasm if prolonged can cause myocardial ischemia leading to malignant arrhythmias such as ventricular fibrillation and ventricular tachycardia resulting in sudden cardiac death (SCD). Treatment for this disorder can be challenging. Current data is lacking on the management of patients receiving appropriate vasodilator medications who present with Ventricular Fibrillation (VFib) as a consequence of coronary artery vasospasms. We present a case of a 71-year-old man who was hospitalized due to recurrent episodes of coronary vasospasms leading to acute decompensation and VFib with subsequent resuscitation while undergoing cardiac catheterization. We also provide review of the literature and updates on the current guidelines from the American Heart Association on this potentially life-threatening disorder.

Abstract
The prevalence of vasospastic angina is said to be low in Europe, but maybe because of a lack of diagnosis in the daily practice. However, coronary spasm is a common cause of cardiac arrest, especially among patients free of cardiac illness, and it should be systematically investigated after an unexplained cardiac arrest. Intracoronary spasm provocation test exposes patients to a lower risk compared to the risk of spontaneous spastic angina. Accurate modalities and diagnostic criteria have to be clarified for European population. Avoiding external causes of coronary spasm (such as cigarette smoking or more generally consuming coronary spasm inducing drugs) and prescribing antispastic medicine (first of all calcium channel blockers) are the basis of vasospastic angina treatment. However, recurrent coronary spasms have been reported despite an appropriate treatment and implantable automatic defibrillator has been implanted after case discussion when the onset of illness was cardiac arrest. We report the case of a patient recovering from cardiac arrest who had a positive spasm coronary provocation test, and was treated with calcium channel blockers and had been an automatic defibrillator implanted, with a coronary spasm provocation test performed afterward still contentious. While discussing this case, we are making a literature review of the diagnosis and treatment of spastic angina revealed by cardiac arrest.

Abstract
In the investigation of sudden death in adults, channelopathies, such as long QT syndrome, have risen to the fore in the minds of forensic pathologists in recent years. Examples of these disorders are touched upon in this review as an absence of abnormal findings at postmortem examination is characteristic and the importance of considering the diagnosis lies in the heritable nature of these conditions. Typically, a diagnosis of a possible channelopathy is evoked as an explanation for a 'negative autopsy' in a case of apparent sudden natural death. However, the one potential adverse effect of this approach is that subtle causes of sudden death may be overlooked. The intention of this article is to review and discuss potential causes of sudden adult death (mostly natural) that should be considered before resorting to a diagnosis of possible channelopathy. Nonetheless, it becomes apparent that many of the potential causes of sudden death can have a genetic basis. Thus, it becomes an important consideration that there may be a genetic basis to sudden death that extends beyond the negative autopsy.

Abstract
Coronary artery spasm can cause both brady- and tachyarrhythmia, through induction of AV block (usually linked to coronary spasm of the right coronary artery) or ventricular tachycardia/fibrillation linked to extensive myocardial ischemia. The electrocardiographic aspect of coronary artery spasm is an ST segment elevation. We describe the case of patient implanted with an implantable cardioverter defibrillator (ICD) for unexplained syncope which, during coronary artery spasm, received an inappropriate device firing due to ST segment elevation, leading to a double count of the QRS by the ICD.

Abstract
BACKGROUND Coronary vasospasm-induced electrical and mechanical complications in patients with acute coronary syndrome and no hemodynamically significant coronary artery disease are rarely reported. METHODS A total of 733 consecutive patients with acute coronary syndrome admitted to our hospital who subsequently underwent coronary angiography at our institution were enrolled. Patients who had documented complete atrioventricular block or ventricular fibrillation, no evidence of hemodynamically significant coronary artery disease on coronary angiogram, and no other (non-coronary) cardiac abnormalities were included. Patients were followed for subsequent cardiac events and mortality. RESULTS Over a 6-year period at our institution, acute coronary syndrome complicated by life-threatening cardiac arrhythmias developed in six patients who had no hemodynamically significant coronary artery disease with corresponding intra-coronary ergonovine provocative coronary vasospasm. Acute myocardial infarction was diagnosed in five of these patients and variant angina pectoris in one. Complete atrioventricular block was the most common complication in these cases, followed by cardiogenic shock with or without right ventricular infarction, ventricular fibrillation, and severe sinus arrest. These complications were corrected with intravenous fluid, intravenous atropine or cardiac defibrillation. During a median follow-up period of 26 months, none of the patients expired or suffered nonfatal reinfarction. Two individuals who did not stop smoking during follow-up developed recurrent angina after self-discontinuation of calcium antagonists. CONCLUSIONS Coronary vasospasm can be a cause of life-threatening cardiac arrhythmias in patients with acute coronary syndrome and no hemodynamically significant coronary artery disease. Coronary angiography with/without intra-coronary ergonovine testing is necessary in acute coronary syndrome patients to identify the underlying pathology and establish appropriate treatment in these cases.

Abstract
OBJECTIVE The clinical features of coronary artery spasm as a cause of cardiac arrest were determined in a prospective study on out-of-hospital cardiac arrest (OHCA). METHODS Coronary angiography was performed at admission in 300 consecutive patients with no obvious non-cardiac cause of OHCA. In survivors with no or minimal coronary artery stenosis, a second angiography with provocation test and electrophysiological testing were performed at 1 month. RESULTS Spasm was demonstrated in ten patients. Diagnosis was based upon (1) spontaneous spasm on the admission angiogram (3 patients), (2) transient significative ST-segment elevation at follow-up in patients with no or non-significant coronary artery lesions (4 patients) and (3) spasm during the 1 month provocation test (3 patients). Six patients survived at 1 month; spasm occurred during a new provocation test in five despite treatment with high dosage calcium channel blockers leading to coronary stenting in two, an internal cardiovertor defibrillator in one, and increased drug therapy with prolonged hospitalization in the remainder. At a mean follow-up of 55+/-27 months, no recurrent cardiac arrest occurred. CONCLUSION Systematic coronary angiograms and provocation tests in survivors of OHCA allow prompt diagnosis of coronary artery spasm. Residual spasm despite treatment with calcium channel blockers is frequent. Therapy should therefore be guided by repetitive provocation tests, and seems to avoid recurrence of cardiac arrest.

Abstract
OBJECTIVES Our aim was to look at the clinical features and long-term follow-up of seven patients without coronary artery disease, who had a history of life-threatening ventricular arrhythmias due to coronary spasm. BACKGROUND Arrhythmic cardiac arrest due to isolated coronary spasm is rare, and there is limited information on the patients affected by this entity alone. METHODS The seven patients were recruited retrospectively from a cohort of survivors of cardiac arrest. None had a history of angina pectoris, structural heart disease or significantly narrowed coronary segments. All had a positive ergonovine provocation test result. RESULTS The patients' mean age was 44 years; three were male and four female. All were habitual cigarette smokers. No arrhythmias were induced on programmed ventricular stimulation; corrected QT interval (QTc) and corrected JT interval (JTc) dispersion were within normal ranges. After the ergonovine provocation test, treatment with calcium channel blocking agents (diltiazem, verapamil, nifedipine or amlodipine) was initiated at a dose determined by titration until a negative test result was obtained. At a mean follow-up interval of 58 months for the total group, six patients remained free of symptoms, whereas the one patient who did not stop smoking had a new cardiac arrest despite treatment for coronary spasm. CONCLUSIONS A favorable long-term outcome may be expected in survivors of cardiac arrest due to coronary spasm, in the absence of significant coronary artery disease. Calcium channel blockers are the most appropriate therapy in these patients. These observations provide further evidence for the role of silent ischemia in cardiovascular death.

Abstract
Experiences in 81 patients with variant angina were reviewed with the goal of determining which clinical features were associated with the greatest risk of angina-linked cardiac arrest (13 patients) or sudden unexpected death (9 patients). The risk of occurrence of one of these actually or potentially fatal events was approximately tripled by the presence of either a history of angina-linked syncope or documentation of serious arrhythmia complicating attacks. An unexpected finding was that the risk was increased 1.5-fold by the absence of high-grade organic coronary stenosis. Cardiac arrest and sudden death are important risks of variant angina, which can occur without the presence of severe organic coronary stenosis. These risks can be reduced by adequate vasodilator therapy that includes a calcium channel blocker.

Abstract
A 37-yr-old woman with an 8-month history of chest pain, unrelated to exercise, was successfully resuscitated from out-of-hospital cardiac arrest due to ventricular fibrillation. Cardiac catheterisation revealed minor coronary artery disease. Ergometrine injection was associated with complete occlusion of the left anterior descending coronary associated with identical chest pain and pronounced ST-segment changes.

Abstract
OBJECTIVES The purpose of this review is to assemble the widely dispersed information about cardiac alternans and to categorize the types and mechanisms of alternans, their clinical manifestations and possible therapeutic implications. BACKGROUND The phenomena of mechanical and electrical alternans have been of continuing interest to both physiologists and clinicians. Recent studies have enhanced this interest because of the reported association of alternans with experimental myocardial ischemia and cardiac arrhythmias. METHODS The review formulates concepts based on extensive review of published studies and personal observations. RESULTS Cardiac alternans has been subdivided into the following four categories: 1) mechanical, 2) electrical, 3) in association with myocardial ischemia, and 4) in association with cardiac motion. Mechanical alternans can be explained by hemodynamic or inotropic alterations, or both. Mechanical alternans in the ventricular muscle is accompanied by alternans of action potential shape. In the Purkinje fibers, action potential duration alternates without change in shape and is determined by the duration of the preceding diastolic interval. However, in ventricular muscle fiber, alternans can occur in the presence of constant diastolic intervals. T wave alternans reflects changes in action potential duration and is frequently associated with a long QT interval. Electrocardiographic manifestations of conduction alternans occur at many different sites within the conducting system and myocardium. During myocardial ischemia, additional mechanisms of repolarization alternans have been proposed. Alternans occurring in the presence of a large pericardial effusion is attributed to swinging motion of the heart maintaining two-beat periodicity. CONCLUSIONS Since its origin as "pulsus alternans" described by Traube in 1872, the definition of alternans has evolved into a term encompassing multiple physiologic and pathologic phenomena that, although united by the term cardiac alternans, diverge widely with respect to etiology, mechanism and clinical significance.

Abstract
A review of the literature dealing with sudden death revealed 19 articles in which ostensibly healthy patients with documented VF unrelated to any known cardiac or noncardiac etiology are reported. Fifty-four patients fulfilling the criteria for idiopathic VF, including 14 patients investigated at our institution, are described. The mean age of patients for studies that reported age data was 36 years, with a male-to-female ratio of 2.5 to 1. Over 90% of the patients required resuscitation, while syncope due to nonsustained VF occurred in the rest. Diagnosis of VF was preceded by syncope in one fourth of the patients. Holter monitoring and exercise stress tests were often unrewarding. Available electrophysiologic data revealed a 69% inducibility rate of sustained ventricular tachyarrhythmias using nonaggressive protocols of ventricular stimulation in most cases. Induced tachyarrhythmias were poorly tolerated, and were mostly of polymorphic configuration. Class IA antiarrhythmic agents were highly effective in preventing reinduction of these arrhythmias. Available figures suggest an 11% rate of sudden death within 1 year of diagnosis. Appropriate antiarrhythmic therapy appears to improve prognosis. Reviewed data suggest that idiopathic VF represents an underestimated cause of sudden cardiac death in ostensibly healthy patients. An international registry of patients with idiopathic VF is warranted.
